hi,
i have 20 computer connected in my office through router,but the problem is ip forwarding is not that much of high through routing process,is there any way to increase ip forwarding through routing process?

Subnetting is basically just a way of splitting a TCP/IP network into smaller, more manageable pieces. The basic idea is that if you have an excessive amount of traffic flowing across your network, then that traffic can cause your network to run slowly. When you subnet your network, you are splitting the network into a separate, but interconnected network. That way, most of the network traffic will be isolated to the subnet in which it originated. Of course you can still communicate across a subnet, but the only time that traffic will cross subnet boundaries is when it is specifically destined for a host residing in an alternate subnet.
CEF is mainly used to increase packet switching speed, reducing the overhead and delays introduced by other routing techniques, increasing overall performance. CEF consists of two key components: The Forwarding Information Base (FIB) and adjacencies.
The FIB is similar to the routing table generated by multiple routing protocols, maintaining only the next-hop address for a particular IP-route.
There are five types of adjacencies:
Null adjacency: Handles packets destined to a NULL interface. Packets with FIB entries pointing to NULL adjacencies will normally be dropped.
Punt adjacency: Deals with packets that require special handling or can not be switched by CEF.
Glean adjacency: Handles packets destined for currently attached hosts, but without layer 2 information.
Discard adjacency: FIB entries pointing to this type of adjacency will be discarded.
Drop adjacency: Packets pointing to this entry are dropped, but the prefix will be checked.
